Personally, I'd play for the out, with a stop on the 5 and then 8:00 on the CB to break out the 8/9. But of the more conservative approaches, this is by far my favorite. The hook plays very big because you can hook behind the 7 with the CB or behind the 8/9 with the 5. With BIH and the 5 near the 8/9, you're a pretty big favorite to get out. In fact, maybe I would play this over the runout.
I know it's my suggestion but I still believe that in the long run in plays better and your the odds on favourite from there even if you don't break open the 8-9 cluster. You got the hammer so keep it.
Playing a low percentage 5-9 might leave somebody a lucky kick carom 9 or even a jump 5-9 combo. My way the 5 is on the wrong side of the 9 for that kind of slop. Making the 5-9 from there is about 20:1, You can still win but don't have too.
